HEPA filters are a great choice for improving indoor air quality, as they are designed to capture microscopic particles with high efficiency. They are especially useful in situations such as water damage, heavy smoke infiltration, high levels of volatile organic compounds, and clean rooms. HEPA filters are also an effective air purification method for those who suffer from asthma or allergies, as they can capture pollen, mold spores, fine dust, pet dander, and other allergens and bacteria. When selecting a HEPA filter or True air purifier system, it is important to check how effective it is at removing 0.3 µm particles. This is because the fibers in a HEPA filter are approximately 0.002—0.5 microns (2—500 nanometers, nm) in diameter.
To put this into perspective, a typical human hair is approximately 50 to 150 microns in diameter, so a HEPA filter traps dust several hundred times thinner. In order to extend the lifespan of a HEPA filter, a prefilter can be included in the configuration that helps remove larger particles, leaving smaller particles to be trapped by the HEPA filter. This was developed during the Manhattan Project in the 1940s when they needed filters that could filter out radioactive particles. The research carried out during the war (and the theory about how HEPA filters work) was carried out by the chemist Irving Langmuir, winner of the Nobel Prize. Therefore, if you are concerned about the overall air quality in your home or office, even without these specific situations, a HEPA filter will definitely improve indoor air quality. HEPA filters are an essential part of any air purification system. They are designed to capture microscopic particles with high efficiency and can help reduce allergens and bacteria in your home or office.
